Doctrine2 - add to product entity parameter with value

Please, could you help me?

I´m looking for the best way, how to add to entity (Product) some parametrs with values.

For example: Product T-Shirt would have parametrs: size: XXL, color: red, material: cotton. How to make tables to have the best result - easy adding parametrs to product and easy filtering products by parametrs.

Thank you for your opinions.

You have two options:

A OneToMany relationship with another entity (recommended)

You may create a new entity called ProductProperty and declare a OneToMany relationship from Product to ProductProperty, like this:

The Product entity

/** 
 * @ORM\Entity
 */
class Product
{

    /**
     * @ORM\OneToMany(targetEntity="ProductProperty", mappedBy="product", cascade={"remove"})
     */
    public $properties;

}

The ProductProperty entity

/** 
 * @ORM\Entity
 */
class ProductProperty
{

    /**
     * @ORM\ManyToOne(targetEntity="Product", inversedBy="properties")
     * @ORM\JoinColumn(name="product_id", referencedColumnName="id")
     */
    public $product;

}

Create an array property in entity Product

Doctrine 2 supports arrays (it serializes the array into a TEXT column). Create a property that behaves like an array:

/** 
 * @ORM\Entity
 */
class Product
{

    /** @ORM\Column(type="array") */
    public $properties;

    public function __construct()
    {

        $this->properties = []; //new PHP array notation, if using older PHP use array()

    }

}
